Grater.



UNITED STATES Patented November 10, 1903.

JACOB EOKHARDT, OF ST. LOUIS, MI$SOURL GRATER.

SPECIFICATION forming part of Letters Patent No. 743,472, dated November10, 1903.

Application filed June 10, 1903 and useful Improvements in Graters, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part hereof.

Myinvention has relation to improvements in vegetable-graters; and itconsists in the novel construction of grater more fully set forth in thespecification and pointed out in the claim.

In the drawings, Figure l is a plan of the grater. Fig. 2 is an enlargedplan'of a portion of the grater. Fig. 3 is a longitudinal section online 3 3 of Fig. v2, and Fig. 4. is a transverse section on line 4 4 ofFig. 2.

The object of my invention is to construct a grater having teeth ofdifferent size on opposite faces of the grater, WhBI'QbYtWO distinctgrating-surfaces are presented, one for coarse grating and the other forfine grating. In detail the device may be described as follows:

Referring to the drawings, 1 represents a plane sheet of metalconstituting the body of the grater, being surrounded by an envelop ingborder or bead 2 and terminating in handles or loops 3. Punched from thebody of the grater and disposed on diagonally opposite sides of a commonopening-4 and located along the opposite faces of the body portion aretwo distinct sets of cutting-teeth 5 5', respectively. The teeth 5 aredeeper than the teeth 5; but in other respects the dimensions of theteeth are the same. As seen from the drawings, each tooth is composed ofa basal cutting-wall, a rear Wall, and two terminal or end walls, thecutting-walls of each pair of teeth 5 5 tending in opposite directionsand the cutting edges of each pair of teeth being serial No. 160,920.(No model.)

disposed substantially in the same plane, which plane is perpendicularto the general plane of the sheet 1, Fig. 3.

By passing the article to be grated over the teeth 5 in one direction(to the right in Figs. 1 and 2) the disintegrated particles of thearticle grated will be discharged through the openings 4. By turning thegrater over and passing the article along the teeth 5' in the oppositedirection the disintegratedparticles will drop through the same openingsonto the surface beneath. Any vegetable-such as horseradish, beets, andthe like- -or spices may be grated coarse or fine, as circumstancesrequire.

I do not, of course, wish to belimited to the precise form of tooth hereoutlined, as that may in a measure be departed from without in any wiseaffecting the nature or spirit of my invention.

Having described my invention, what I claim is- A grater comprising abody portion or sheet, and teeth disposedin pairs on opposite faces ofthe sheet, each pair of teeth being lo- .cated adjacent to, and ondiagonally opposite sides of a common discharge-opening, those on oneface being adapted to grate coarser than those on the opposite face, thecutting edges of each pair of teeth being disposed in a plane at rightangles to the plane of the sheet, and each tooth having a rear wall, twoterminal parallel walls substantially uniform in depth with said rearwall, and a cuttingwall, the parts operating substantially as, and forthe purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.I
